AUTO-WHEEL Specification of Letters Patent.

Patented Mar. 11, 1919.

Application filed January 26, 1918, Serial No. 213,987. Renewed December 16, 1918. Serial No. 267,016.

Thisinvention relates to wheels for automoblles and motor vehicles and it has particular reference to wheels for heavy trucks, armored cars and the like which, owing to their weight, are liable to have their prog-' ress impeded when traveling over soft, boggy, marshy or sandy territory.

The invention has for its object to produce a wheel of simple and improved construction which will be provided with extensions an. extremely broad tread and which wi be so constructed as to prevent sinking in soft or sandy soil and which when the soilis wet and clayey will'tend to shed the dirt instead of letting it adhere as is the case with wheels of ordinary construction.

' A further object of the invention is to produce a wheel embodying in its construction an ordinary hub, rim, spokes and tire together with extension members whereby the improved tread is produced and means for bracing and assembling the parts.

A further object of the invention is to simplify and improve the construction and assemble e ofthe parts entering into the construction of the improved wheel.'.

With these and other ends in view .which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings:

Figure 1 is a vertical sectional view of a wheel constructed in accordance with the in- Corresponding parts in the several figures are denoted by like characters of reference.

In the constructlon of the improved device an lordlnary automoblle wheel ma be employed, the same including the hu 15', rim

16, spokes 17 and'tire 18, the latter having been shown as consisting of a solid rubber tire although within the scope of the invention any well known form of tire may be used. It will also be understood that in view of a wheel having spokes, solid disks of modeifn construction may be employed. The improved attachment comprises a pair of extenslon members A each consisting of a cupshaped or funnel-shaped disk 19 having a circumferential flange 20 which tapers from the: edge of the disk in an outward direction .so that the diameter of the edge portion of the flange :20 will materially exceed the diameter of the disk 19 at the edge thereof. The disk 19 has a central aperture 21 surrounded by a flange 22 adapted to fit snugly upon the hub 15 of the wheel .in connection with which the device is to be used.

Securely bolted upon or otherwise con-- it I I v, asst ar :disks 19and the flanges 20;

Each of the extension members of the tread, members is provided with an interiorly disposed annular brace 27, stamped or formed of sheet metal and preferably having radial slots 28 formed therein for the purpose of lightening the same without materially decreasing the strength thereof. Tlie annular brace members are provided with the flanges 29 which are riveted or otherwise secured on the disks 19 and with the flanges 30 which are riveted or otherwise secured on the flanges 20, the said flanges 20 and 30 being provided with interengaging countersinks 31, 32 the form of which will accommodate the head of the bolt, rivet or other connecting member 33 so that the flange 20 will exteriorly present a smooth surface.

It may be stated that the extension members or tread members as well as the annular brace members 27 may be stamped or i. otherwise formed of sheet steel or other material possessing the necessary requisites of strength and durability [without excessive weight. The parts, when constructed and assembled as herein described, will present a wheel having the tire 18 which functions with the roads when they are in good condi tion. The flanges 20 of the tread members will diverge upwardly with respect to the road engaging portion of the tire 18 to such an extent that they will not ordinarily come in contact with loose stones, and other obstructions on the road surface. lVhen the territory traversed is muddy, boggy. sandy or otherwise of a yielding nature to such an extent that the tire 18 will sink therein. the flanges 20 of the tread member come into play, said flanges presenting a tread surface of such width that bogging or miring of the vehicle equipped with the improved wheel will ordinarily be prevented. The peculiar shape and construction of the tread members is also of such a nature that dirt of a clayey and sticky nature will ordinarily be shed without adhering thereto.

In order to increase the strength and durability of the device it is preferred that. the annular bands which serve for the attachment of the tread members to the wheel be provided with webs or braces 34 whereby the wings '24 andvifi are connwn-d together, as clearly indicated in Fig. 1 of the draw- .ings.

disk having a central aperture surrounded by afiange.

3. A tread attachment for automobile wheels, comprising a funnel-shaped disk having an outwardly tapered flange, said disk having a central aperture surrounded by a flange; in combination with an annular b ace member having flanges secured respectively on the disk and on the outwardly tapered flange thereof.

4. A tread attachment for automobile wheels. comprising a funnel-shaped disk having an outwardly tapered flange, said disk having a central aperture surrounded by a flange; in combination with an annular brace member having flanges secured respectivel v on. the disk and on the outwardly v tapered flangethe'reo'f. said annular brace nieniberbeing provided with radial slots.
